The sun peeks over the horizon on a beautiful day in Britain in Godalming, Surrey

Dr Penny Woods, chief executive of the British Lung Foundation said: “During very warm weather, people living with lung conditions may find high temperatures mean their symptoms get worse.

“This can be because they’re too hot, dehydrated, or because of high ozone levels in the air.

“If you have a lung condition, we advise keeping out of the sun and avoiding the heat.”

Met Office meteorologist Emma Sharples told The Sun Online: “There will be quite a lot of settled weather around and increasingly as you go into the week more in the way of sunshine and then more in the way of warmth as well as we get a flow developing from the south.

“This will bring continental air up so by the end of the week we will be seeing temperatures in the mid to high twenties and probably into the low thirties in the south as we go into Saturday.
